 **isLength(str [, options])**              | check if the string's length falls in a range.<br/><br/>`options` is an object which defaults to `{min:0, max: undefined}`. Note: this function takes into account surrogate pairs.
 **isLocale(str)**                       | check if the string is a locale
 **isLowercase(str)**                    | check if the string is lowercase.
-**isMACAddress(str)**                   | check if the string is a MAC address.<br/><br/>`options` is an object which defaults to `{no_colons: false}`. If `no_colons` is true, the validator will allow MAC addresses without the colons. Also, it allows the use of hyphens or spaces e.g  '01 02 03 04 05 ab' or '01-02-03-04-05-ab'.
